Nov. 11, 1930. J. E. MACKIE ET'AL FLOOR SLEEPER Filed March 3, 1930 N Amm mm m B Y Y zrjomvs v Patented Nov. 11, 1930 UNITED STATES PATENToFFI'CE JAMES E. MAGKIE AND AARON 3'. SMITH, LONG- BEACH, CALIFORNIA-FLOOR SLEEPER Application filed March 3,

This invention relates to a floor sleeper, screed and furring stripwhich is adapted to be positioned in a concrete floor or in a wall. Whenin position, the sleeper afiords'a means for securing flooring and thelike over a concrete base, or to secure wall covering or trimming whenused as a furring strip.

An object of our invention is 'to provide a sleeper of the characterstated which can 10 be quickly and easily placed in position in thefloor or wall, and when placed in the floor will materially reduce theoverall height of a building. Another ob'ect is to provide a sleeperwhich can also be eflectively used as a screed for the concrete orcement floor.

An advantage of our sleeper is that it may be installed in multiples,thus materially decreasing the time necessary to install the sleepers.

Another advantage of our sleeper is that it is securely anchored in theconcrete.

Other objects, advantages and features of invention may appear from theaccompanying drawing, the subjoined detailed description, and theappended claims.

In the drawing Figure 1 is a transverse sectional view of a pair ofsleepers in operative position, and

with the flooring secured thereto.

Figure 2 is a transverse sectional View of a slightly modified form ofsleeper.

Figure 3 is a side elevation of one of the sleepers. I V

Figure 4 is a plan View of a plurality of sleepers secured to masterstrips prior to installing.

Referring more particularly to the'drawing, the numeral 1 indicates ametal case, 40 preferably formed of acomparatively light sheet metalwhich can be readily stamped into the shape desired. The case is formedinto a substantially rectangular trough 2 in which a wooden strip 3 isplaced. The strip 3 is preferably creosoted so as to materially lengthenits effective life. At the upper end, the case 1 is bent outwardly intoflanges 47-4 and these flanges are bent downwardly at their outer endsto form spacing ribs 5. As 50 shown in Figures 1 and 2, the concretefloor 1930. Serial 116.432,?32;

comes to the level ofthelower 'edge of the spacing ribs 5, and theseribsthus provide a screed to lev'elfloff the concrete floor, as will bedescribed in detail later. To securely anchor the case 1 intotheconcrete floor or wall 6, we provide at the lower edge of the caselongitudinally extending anchor ribs 7 The anchor ribs ar'e integrallyformed with the metal case, and as w'ill be evident, provide anefle'ctiv'e' means against removal or displacementof the sleeper. Theflooring or the like 8 is placed over the sle'epers and nails 9 are.driven'through the floor. ing into thewooden strip 3 and the nails asthey come in contact with the bottor'n of the case 1, will be clinchedover as shown in Figuresland2. j,

To hold the wooden strip 3 securely in the case" 1,"we provide aplurality of cars 10 which are cut out ofthje sidesiofth'efcase, and aredrivenijnwardly into the wooden, strip, thus securely holding it against1displace ment. ,7 M p p Our sleepers may be positioned in'thefollowing'mannerr A plurality of the, sleepers are secured to masterstrips ll llb'y means of nails which extend'through the flanges l. Themaster strips and theattachedjsleepers are leveled by any suitable and'well-kfnown means, after which the concrete flooring is poured, Theribs: 51act'as a screed togage the top surface ofthe floor.

A slightly'modified form of sleeper is 7 shown in Figure 2. The metalcase 12 is stamped into'the shape of a truncated'prism in cross section,I and the wooden strip 13 conforms in shape to the metal case; By thismeans the wooden strip is securely held in position without requiringthe cutout ears as previously described. Outwardly extending flanges 14-14 areprovided at the upper end of the case, and these flanges areturned downwardly into spacing ribs 15 which are identical inconstruction to the flanges 4 and ribs 5.

Having described our invention, we claim:

1. A sleeper or strip comprising an elongated metal case, said casebeing formed in the nature of a trough, a wooden strip secured in thecaseand depending ribs at, the upper end of said ease.

2. A sleeper and strip comprising a metal case formed into an elongatedtrough, a wooden strip positioned in the trough, outwardly extendingflanges at the upper end of thecase, said flanges being bentdownwardlyinto depending ribs, 3'.
